Understanding profit
How OneDS works out your profit, margin and ROI, and what the minimum profit does.
Profit is your eBay price, minus the Amazon cost, eBay's fees at your rate, the promoted-listing cost and any other costs you set in Settings.
Margin and ROI
Margin is profit as a share of your eBay price. ROI is profit as a share of what you spend on the item.
Minimum profit
Anything under your minimum is flagged before you list. Orders that fall under it, for example because the Amazon price went up, wait for you instead of going ahead. The minimum is at least £2 and you can raise it in Settings.
